Ag-grid : get column index of clicked cell

Hi all,
I am trying to get the index of a cell when clicked. I am able to get the row using the return of AgGrid. I am also able to get the row and the column of the clicked cell using JS code but I cannot send the data to the streamlit code.

import streamlit as st
import numpy as np
import pandas as pd

from st_aggrid import AgGrid, DataReturnMode, GridUpdateMode, GridOptionsBuilder, JsCode

def generate_df():
    df = pd.DataFrame(
        np.random.randint(0, 100, 30).reshape(-1, 3), columns=list("abc")
    return df

data = generate_df()

gb = GridOptionsBuilder.from_dataframe(data)
gb.configure_columns(list('abc'), editable=True)

js = JsCode("""
function(e) {
    let api = e.api;
    let rowIndex = e.rowIndex;
    let col = e.column.colId;
    let rowNode = api.getDisplayedRowAtIndex(rowIndex);
    console.log("column index: " + col + ", row index: " + rowIndex);

gb.configure_selection(selection_mode ='single')
go =

return_ag = AgGrid(data, gridOptions=go, allow_unsafe_jscode=True, reload_data=False, update_mode=GridUpdateMode.SELECTION_CHANGED)


params returned by AgGrid:

And the console in Inspect with the correct column and row indexes:

Any suggestions?


I’m also trying to do this but without luck

ok maybe this might help: Although I don’t get the index in the example, I am sure it might work the same way…

this part taking from code that I found here…

def aggrid_interactive_table(df: pd.DataFrame):
“”"Creates an st-aggrid interactive table based on a dataframe.

    df (pd.DataFrame]): Source dataframe

    dict: The selected row
options = GridOptionsBuilder.from_dataframe(
    df, enableRowGroup=True, enableValue=True, enablePivot=True
#editable = True was removed - need this to be non- editable

selection = AgGrid(

return selection

Then In my code I have the following (I am doing a parent/child form think invoice header/line items)

get the GUID (ID) of the selected row and filter the child row based on that

if selection["selected_rows"]:
    c = selection["selected_rows"][0]["ID"]
    if c > 0:
        st.write(df3[df3['ID'] == c])

What the code is setting c = the “ID Field” i have in the parent Dataframe that is selected. I had to use 0 for the first even thought I am only allowing on selection. and From there I pass it to 2nd dataframe. I have not tried with index, but though this would help. (BTW I started with streamlit yesterday and just learning)

That will simply assign the value in column ‘ID’ of the selected row to c. This will happen regardless whether the clicked column was ‘ID’ or something else, so I’m afraid this won’t help.

I have the same problem. It seems that class AgGridReturn only return row info but col info. Have you solved it?Looking forward to your early reply
class AgGridReturn(Mapping):
“”“Class to hold AgGrid call return”“”
data: Union[pd.DataFrame , str] = None
selected_rows: List[Mapping] = field(default_factory=list)
column_state = None

Did you ever get anywhere with this? I’ve been trying to work this out for a while now

Does someone have an update about it?

I would be interested on this too

It’s incredible that a grid control won’t give you the column of the cell clicked! It’s laughable. Why do you people use this thing? it’s a toy

Is there any update on this issue?
